3. Top 5 tips for opening lunch boxes that are hotly discussed on the Internet
1.thermal expansion and contraction method: Soak the lunch box upside down in hot water for 1 minute, and it will automatically pop open using the air pressure difference. Douyin’s actual test video shows that this method has been praised by 97% of users.
2.Rubber band friction method: Wrap a thick rubber band around the edge of the lunch box lid to increase friction. Xiaohongshu experts recommend this method, especially for people with slippery hands.
3.Hair dryer heating method: Blow hot air against the sealing ring for 20 seconds to soften the silicone. Zhihu physics experts pointed out that this method is consistent with the principles of material thermodynamics.
4.Spoon Leverage: Insert a metal spoon into the gap and gently pry it. The Weibo topic #一 spoon opens the lunch box # has been read 230 million times.
5.tapping method: Quickly tap the bottom of the lunch box with your palm in a cup shape to release the seal through vibration. The main test of Station B UP shows that the optimal flapping frequency is 3 times/second.
4. Purchase suggestions to prevent lunch boxes from being unable to be opened
| Purchasing factors | Recommended parameters | Tips for avoiding pits |
|---|---|---|
| Sealing method | Adjustable air pressure valve | Avoid pure negative pressure design |
| open structure | Double ear buckle design | Choose hidden switches carefully |
| Material combination | PP+silica gel | Avoid all-metal integration |
| Additional features | Pressure relief indicator light | Simplifying smart lock design |
5. Solutions for special scenarios
1.Cannot be opened after freezing: Wrap the lunch box with a towel and rinse it with warm water for 30 seconds. Be careful to prevent the glass lunch box from bursting due to sudden heat.
2.No tools in the office: Use the computer USB port to heat the metal key and insert it into the gap to melt the ice crystal and seal it.
3.Outdoor emergency response: Place the lunch box in the sun, or use a carabiner as a fulcrum.
4.Child safety on: Choose a children’s lunch box with a rotating pressure relief valve to educate your children on the “turn first, then open” principle.
By analyzing the hotspot data on the entire network, we can find that there is interesting physics knowledge and life wisdom behind the lunch box opening problem. Once you master these methods, you’ll never have to deal with an unopened lunch box again!
